I recently learned how the Pfizer Coronavirus vaccine works. It’s genius. I should add the following disclaimer: Pfizer is one of my clients.
When scientists looked at Covid-19 cells they discovered each cell has an identical protein. The virus cell relies on this protein.
Each time we get any infection, our immune system sees it as a foreign enemy and rushes to kill it.
But first it must find the best way and then gather resources to wage the war.
Unfortunately this isn’t instant. It takes time for the immune system to fight back. In the meantime, the infection is free to do damage.
The human immune system also has another important weapon: memory cells so it knows how to recognise the virus in the future.
Pfizer scientists came up with a vaccine that comprises one ingredient. Instructions to the body to make the foreign protein essential to the Covid-19 virus cell.
When you receive the injected protein instructions in vaccine form, the body makes it and then the immune system rushes to kill it and remember what it is for future reference.
Cell memory becomes very important in dealing with Covid. Having killed the protein, the immune system now instantly recognises it in any other form like when it’s attached to a Covid-19 cell and immediately kills the infection before it can do damage.
The genius is in the science.
